DESCRIPTION;

' tion.

The present invention isdirected to an im-..

proved receipt printin and issuing or feeding mechanism for cashregisters and/ or account ing machines, which improved mechanism iscontained as a compact unit in a box-shaped drawer which also forms areceptacle or magazine for the supply of: receipt material, which inthiscase is a. package. of fanfolded receipt paper. The printer drawer ismovable from closed or operating position outwardly to open or a moreaccessible position for the adjustment of the mechanism containedtherein, for the insertion ot a. new. supply packageof. receiptmaterial, and for the convenient threading of the web of the receiptmaterial over the printing and feeding mechanism. If desirable ornecessary, the printer drawer may be readily removed from the. ma.-chine by moving said drawer inwardly a slight distance from fully openposition and lifting up on said drawer, and then withdrawing itoutward-1y until free of the machine. end of the printer drawer forms ahinged door orclosure which. is normally latched in closed position,but, when said drawer is open, the door may be unlatched and, opened togive access to The present machine is provided with the usual type ofmanually positionable control lever for controlling the variousfunctions of the machine, and controllin mechanism is provided whichmakes it impossible to move the printer drawer to closed. or operatingposition unless the control lever is in either Read or Reset position.

The machine chosen toillustrate the present invention is apress-down-key type of cash register ofcomparatively simpleconstruction. However, it is not the desire nor the intention toconfineapplicants" improved mechanism to any particular type of machine, aswith minor ad-= justments and alterations it may be adapted for use inpractically anytype of cash register and/or accounting machine.

Framework The framework of the machine comprises a left side plate 30(Figs. 1 and 2) and a right side plate 3*! maintained in parallel andvertical re- I lationship to each other by front tie bars (not terialand the mechanism for advancing; the

consecutive number type. wheels, which along with the other type. wheelsaresupported in the main portion of the machine, asialso are the inkingribbon and its feeding mechanism for, the inking of. said type. wheels.and. saidv electro,

The. simplicity and accessibility of. the. im-

proved receipt printing mechanism make, it a comparatively simplematterto. install. newv receiptmaterial in the machine. Withthe drawerin open position, as shown in Fig. 2,, thedoor giving access to theinterior of. said. drawer is opened, and the pack. of fanfolded receipt.material is inserted within said drawer. The. door is then closed, and.another door. onthetop. surface of the printer drawer provides another.convenient opening to the interior of. the drawer through which theoperator may pick up the webof the fanfolded. receipt. material and"carry said web forwardly across the. printing hammers and the feedingrollers, thence through aguide I I chuteformed by the upper portion, ofthe printer drawer. After this, it is only-necessary tov close the.printer drawer, to condition the. machine and the receipt mechanism foroperation. The driving or. operating. mechanism. for theimpressionhammers, for the receipt.feeding.mechanism,v and for the consecutivenumber type wheels is conshown), by a back frame 32 and by variousshafts and rods which extend between said side plates 30 and-31'. Themachine framework, comprising the two sideplates 30 and 3|, the backframe 32, and the various tie bars and rods, is secured to the topsurface of a drawer cabinet 33 (Fig. 2), and the mechanism of themachine is enclosed by a suitable cabinet 34, which is in turn securedto the machine framework.

Key mechanism in general The present machine is provided with aplurality; of amount, keys 35 (Figsl and 2) of the so-called five-centkey. arrangement, including'keys arranged in multiples of five, fromfive cents to ninety cents,and one-, two. and threedollar keys, The keysof the present machine also include a Paid-out transaction key 36, aNo-salejtransaction key 36, and two department or clerks keys 31, whichlatter control the selection of'the two totalizers withwhich the presentmachine is equipped, The keys are rockably supported. on a shaft 38'journaled in the plates 36 and 3|. I

In the present'arrangement, the amount keys comprise threedenominationalorders, each of whichcontrols corresponding differentialmechanisms for positioning corresponding type wheels andindicatorsandfor entering the representative values thereof; into thejcorresponding'totalizer wheels. Likewise th'e'tr'ansaction' keys '36 and It islikewise necessary to the department keys 31controlcorrespondlngdifferential mechanisms'which in turn position corresponding type wheelsand indicators.

Key coupler mechanism As previously explained, the machine embodying thepresent invention is of the press-downkey type and isprovided with thewell-known key coupler mechanism for connecting the depressed keystogether during a machine operation and for blocking depression ofundepressed keys during machine operation, said key coupler through itsweight also assisting in returning the keys to undepressed position(Fig. 3), and in which a finished surface on the inward ends of the keys35, 36, and 31 rests on a corresponding finished surface 39 on the backframe 32. Each of the keys 35, 36, and 31 has therein a slot 4|, whichcooperates with the inward end of a key coupler 42, rotatably mounted ona shaft 43, supported by the plates 3|] and 3| (Figs. 1, 2, and 3).Normally, the weight of the key coupler 42 bearing on the lower surfaceof the slot 4| in the keys 35, 36, and 3'! yieldingly retains said keysin undepressed or home positions, as shown here. i

Yieldingly retained in a recess in the upper inward edge of the keycoupler 42 (Fig. 3) is a bar 54, for each denominational order of amountkeys, one for the transaction keys and one for the department keys,which bars coact with the upper edges of the slots 4| to provide asemi-flexible key arrangement which does notrequire that all of theamount keys involved in a single transaction be depressed at the sametime. Depression of any one of the keys 35, 36, or 3'! a slight distancecauses the lower surface of the slot 4| therein, in cooperation with theinner end of the key coupler 42, to rock said key couplercounterclockwise a slight distance. Inasmuch as the key coupler 42swings on a different axis from the keys, the upper edge of the slot 4|of the key being depressed moves over or by-passes the correspondingyieldable bar 54, and, inasmuch as a full-stroke device, to be describedpresently, prevents retrograde movement of the key coupler 42, furtherdepression of said key may be postponed in case it is desired to depressother keys in different denominations, which likewise may be partiallydepressed, one at a time, and retained thus by their correspondingyieldable bars 54. After all of the desired keys have thus beenpartially depressed, full depression of any one of said keys, throughthe wellknown action of the key coupler 42, in cooperation with theslots 4| of the partially depressed keys, will complete the depression.of said keys in unison and will also complete the initialcounter-clockwise movement of said key coupler 42. Each of the keys 35,36, and 31 (Figs. 1, 2, and 3) has an arcuate surface 55, just above thecorresponding slots 4|, which surface is con centric with the pivotcenter 43 of the key cou pler 42. Consequently initial counter clockwisemovement of said key coupler, upon depression of any one of the keys,causes the inner edge of said key coupler to move opposite the arcuatesurface 55 and to obstrnct depression of any undepressed keys duringmachine operation. After the desired keys have been fully depressed, re-

lease of the pressure on said keys permits the weight of the key coupler42, assisted by springs inot shown), to efiect its clockwise returnmovemerit to return the depressed keys'tohome' post-,- tion. Eachdenominational order of amount keys has a series of the usual andwell-known key stops (not shown) coacting with rearward projections 44(Fig. 3) on said keys, to prevent depression of more than one amount keyin each denominational order at the same time. Likewise the transactionkeys 36 (Fig. 1) and the department keys 31 have corresponding sets ofkey stops to prevent depression of more than one of these keys at thesame time.

Rotary shaft operating mechanism teeth of the pinion 49, secured on arevolution shaft 50, journaled in the side plates 30 and 3|.

,A spring 5|, tensioned between a forward extension of the lever 45 anda rearward extension of the pitman 46, urges said pitmancounterclockwise, when said parts are in home position, as shown in Fig.4, to normally maintain the teeth 47 in engagement with the pinion 49. vj

Initial counter-clockwise movement of the key coupler 42 and the lever45, upon depression of a key, as explained earlier, moves the pitman 46upwardly, causing the teeth 41, in cooperation with the pinion 49, torotate said pinion and the shaft 50 in a counter-clockwise direction.

Immediately after the pitman 46 starts its initial upward movement, abent-over ear 52 thereon passes over and slides on the outer surface ofa guide bar 53 secured to the right plate 3|, to

retain the teeth 41 in engagement with the pinion 49 during initialmovement of said pitman 46.

After the ear 52 has moved over the bar 53,

and just prior to termination of initial counterclockwise movement ofthe key coupler 42, the

lever 45, and the pitman 46, the pivot center of said pitman moves abovethe centerline, or line of pull of the spring 5|, and as a result saidpitman 46 is immediately urged in a reverse or clockwise direction. Nearthe terminus of initial counter-clockwise movement of the key couple'r42, the lever 45, and the pitman 46, the ear 52 (Fig. 4) moves beyondthe bar 53, whereupon the spring 5| rocks said pitman 46 clockwise todisengage the teeth 41 from the pinion 49 and to simultaneously engagethe teeth 48 with said pinion.

Just at the end of initial counter-clockwise movement of the key coupler42, the lever 45, and the pitman 46, and approximately simultaneouslywith the shifting of said pitman 46, an angular alining surface 40 (Fig.4) on an upward extension of said lever 45 engages a corresponding amen?pier =42 and associated parts, including the keys 35, 36, and 31.

Clockwise return movement of .thekey coupler 42, the lever 45, and thepitman '46 causes the teeth 48, in cooperation with the teeth of thepinion 49, to continue operation of .said pinion and the .shaft 58 in acounter-clockwise direction to complete the revolution of said .iparts..At the beginnin'g of the downward return movement of the pitman 46(Fig. 4),, theear 52 passes beheath .the inner :surface of the bar 53and, in cooperation with said bar, retains :the teeth48 in engagementwith the pinion 49 during such return'movemerit of said pitman. Asithelpitman 46 .is being returned clockwise, its pivot point movesbeneath the centerline or line "of jpullof the spring? I whereuponsaidspringagain urges said'pitman in a counter-clockwise direction. As the.pitman 46 nears the end "of its clockwise "return movement, the car 52movesben'eath .the bar 53 (Fig. 4), whereupon the spring 5| rocks saidpitman counter-clockwiseto-"disengage the teeth 48 from the pinion49"and to simultaneouslyreengage'the teeth with said pinion.

A full-stroke device, including aratchet (not shown) secured on therevolutionshaft 58 (Fig 4) and a pawl coactingtherewith,"prevents'retrograde movement of said shaft and connectedparts to insure that said 'parts,'inc1udihg thekey coupler 42, perform"a complete cycle of operation each machine operation. The full strokedevice, in cooperation with the yieldable bars 54 (Fig. 3) retains thekeys 35, 36, and'3l partially depressed, as explained in-conn'ectionwiththe semi-flexible 'a'ction'of said keys, so that" additional keys may bedepressed prior *to complete operation of the machine.

The 'three consecutivevnumber type: wheels8fl each of said wheels hassecured thereto a feed ratchet 8I with teeth which cooperate with thecorresponding one of three graduatedteeth on a feed pawl 82 free on astud 83 extending between the side arms of a yoke 84, said arms beingfree on the shaft I6 and straddling the three consecutive number typewheels 80. A clearance cut is provided in the feed pawl 82 for a torsionspring 85; whichencircles the stud 83 and urges said pawl 82 clockwise(Fig. 15) to normally maintain the teeth of said pawl in yieldingengagement with the ratchets 8|.

An extension of the right arm of the yoke 84 (Fig. 14) carries astud 89, which cooperates with a cam slot 90 in an arm 9'I secured onthe shaft 66. Also secured on the shaft 66 is a crank 92, pivotallyconnected by a link 93 to a lever 94 free on a stud 95 (Figs, 1, 5, and7) secured in the right plate 3|. 7 Y

Rocking movement first counter-clockwise and back to normal position ofthe lever 94, as will be explained later, through the link 93, rocks thecrank 92, the shaft 66, and the arm -9I' also counter-clockwise andback'to normal position. Rocking movement of the arm 9I (Fig.14) bymeans of the cam slot 90. in cooperation with the stud 89, rocks theyoke 84 and thefeed pawl 82 back and forth (Fig. 15), causing the toothfor the units order wheel. in cooperation with the teeth of thecorresponding ratchet BI. to advance said wheel one ste in a clockwisedirection for each operation of the machine.

' slot I I 2 in a disk I I3 secured on a shaft I I4, which extendssubstantially the full width of the machine and is journaled in the leftand right plates and 3 I' (Fig. 1). Secured on the left-hand end of theshaft II4 (Fig. 12) is a pinion H5, which meshes with teeth formed on aninternal arcuate surface on an extension II6 of a machine control leverI I7 pivoted on a stud I I8 in the left plate 30.

By referring to Fig. 12, it will be seen that the control lever I I! hasfive positions; namely. Open-drawer position, in which it is shown hereand in which position the machine may be operated with the cash drawereither open or closed; Closed-drawer position, in which the machine maybe operated only when the cash drawer is closed; Locked registerposition, in which the machine is locked against operation; Readposition, in which either of the totalizers may be read; and Resetposition, in which either of the totalizers may be reset. i The controllever I I! (Fig. 12)

is provided with 'a' lock and a corresponding key the $1.00 key 35 Afingerpiece I00, formed on a forward extension of the lever 98, extendsthrough a clearance slot in the cabinet34 (Fig. 2)v to serve as a mediumfor manually rocking the. reset lever 98 first clockwise andthen back tonormal position- The lever 98 has. on its periphery,.teeth which meshwith the teeth of a pinion I 0| secured on" the ri ht-hand end of the.shaft 16. The shaft. I6 (Fig 15) has formed thereon a longituq possessorof the key H9 may move the control lever I I! to any of its variouspositions, including Read and Reset positions.

Moving the control lever II! to either Read or Reset position revolvesthe shaft H4 and the disk II 3, causing the cam slot II2 (Figs. 12 and13) in said disk H3, in cooperation with the stud III, to rock the leverI09 clockwise from the position shown here to the position shown in Fig2. Clockwise movement of the lever I09, through the link I08, rocks thearm I01, the shaft 66, and the crank I05 also clockwise to move the studI04 out of the path of the shoul der I03 (Fig. '2) to freetheconsecutivenumber reset lever 99 for manipulation. Resetting of the consecut venumber type wheels requires a'clockwise pickup movement of the resetlever 98' and a counter-clockwise resetting movement ef'said lever.Clockwise movement of the lever 90, through the'teeth thereon, rotatesthe pinion IN and the shaft 16 counter-clockwise to cause the resettingshoulder on'said shaft I6 to bypass theiteeth of the reset pawls I02 forthe consecutivenumber type wheels which are out of zero position.Counter-clockwise return movement of the reset lever 98 revolves thereset shaft I6 clockwise, causing the reset shoulder on said shaft toengage the teeth of the reset pawls I02 for the wheels 80 out of zeroposition. and carry said wheels also clockwise in unison therewithtozero position. When the consecutive number reset lever 98 (Fig. 13) isout of home position, an arcuate surface I20, formed onsaid leveradjacent the shoulder I03, in cooperation with the stud.

I3I:on at right-hand feed pawl I32 pivoted to an operating 7 arm I34 free onthe shaft 66. The left-hand! ribbon sp'ool' I has a" similar ratchetI35, thei, teeth of which coact with afeeding' extension; $35 of aleft-hand feed pawl I31 pivoted to their arm I34; The arm I34 (Figs; 6;'7, and 8) car- .5 40 ries a stud I39, which engagesa reduced portion fof a slot I40 in an arm MI, an enlarged portion of said slot I40 freelyengaging the sha-ft 66. spring I42, tensioned betweenthe arm MI and. anoperating arm I43 free on the shaft 66, urges, said arm MI upwardly tonormally maintain an operating nose I44 thereon in-the pathof a study M5in saidarm I43. The arm' I43 has, in'a; downward extension thereof, acam: slot I43; 1 I. engaged by a stud m1 in the um; as, which,.aspreviously explained, forms an operating cone nection between the lever94, the crank 92,. and. the shaft 66'.

Rocking movement of the lever 94 first court ter-clockwise and back tonormal position during machine operation, and effected in a manner to bedescribedla-ter, shifts the link 93 first downward y and then upwardly,causing the stud I41, in cooperation with the cam slot I46, to-rock thearm I43 first counter-clockwise and then back to normal position.

Receipt material drawer mechanism supply of issuing receipt materialI29. (Figs; 1,. 2-, and 2 is preferably of. fanfolded arrangement toforma compact rectangularpackagewhich may, if desired; becontained in:

azpaper'box" Hit-having an opening atlthe top for the dispensing of saidmaterial; in: much the-same: manner as cleansing tissue is packaged anddispensed. The: fanfold package I 53 is readily in-- sertablein. amagazine or' drawer I'-5-I formed preferably of. sheet-material andhaving a bottom I52, side plates I53, afront door or closure- I54 forthe insertion of the package of receipt mate rial, and a: top door I55for the convenient. threading of the web of the receipt material overtheiimpressioni hammers 1'9 and I22 and the receipt material. feedingrollers, The sides, bottom, and rearward end of the receipt-materialdrawer t5! may be secured into a rigid structure by spot welding,riveting, or any other suitable means. The receipt-material drawer I5-Islides back and forth through an. opening I56 in the front of the.cabinet 34 on a pair of parallel rails I51, which engage the bottom I52of said: drawer, said. rails being secured to the machine framework.Flanaes I158 (Fig. 2), formed by downward ex-. tensions of thesideplates I53, fit. closely within the: rails I51 and cooperatetherewith to guide the drawer I 5| in. its. sliding. movement and toprevent excessive side displacement of said drawen. Each. side plate I53has a downward extension 159 one. 2), each carrying a stud .I-GB, saidstuds cooperating with correspondin flanges I'6If formed on the railsI51 to sustain the overhanging weight of the drawer I'5I when itispulled forwardly, as shown here. Downward extensions I62 on the forwardends of the flanges IGI, in cooperation with the studsI 60,. determinethe extent of the forward or opening movement In addition to theextensions I92, hooks extending upwardly from the rails I51 coact withcorresponding studs I (Fig. -2) in the side plates I53 to assist interminating the opening movement of the drawer I5I. Openings I63, formedin the forward edges of the flanges I The front door or closure I54(Fig. 2) is hinged by means of rightand left-hand brackets I64 (only oneshown here) secured thereto, in cooperation with pivot studs I65 securedin the right and left side plates I53 of the drawer I5I.

The closed position of the door I54 is determined by stop surfaces onthe brackets I64, in cooperation with corresponding stop studs I56secured in the side plates I59. The open positionof the door I54 isdetermined by means of fingers I61 H on the brackets I64, in cooperationwith the studs I66. The door I54 is latched in;,closed position, asshown in Fig. 2, by hooks formed on the brackets I54, in cooperationwith corresponding studs I68 carried by corresponding latches I69 (onlyone shown here) pivoted on studs I19 in the side plates I53. The latchesI69 have corresponding springs I1 I, which urge them counter-' clockwiseto normally maintain a finger I12 thereof in contact with thecorresponding studs I 66 to determine the effective positions of saidlatches I69.

When the receipt material drawer I5I is open, as shown in Fig. 2, thelatches I69 may be manu ally moved clockwise against the action of theirsprings I1I to lift the studs I68 out of the path of the hooks on thebrackets I64, whereupon the door I54 may be opened for the purpose ofreplenishing the supply of receipt material b removing the emptycontainer or box I50- and inserting a new box with a full supply ofreceipt material therein. If desired, a slot I84 (Fig. 20) may beprovided in the door I54, which, with-a matching slot in the end of thebox I (Fig. 21),

provides visual means for determining the conon a, pin I13, and, whenthe record material drawer I5I is open, as shown here, said closure Imay be opened to provide finger 'room for.

reaching within the drawer I5I and .the box I50 to retrieve the web ofthe receipt material I29 and carry said web over a guide plate I14,secured between the side plates I53, thence over the impression hammers19 and I22 and the feed rollers I16, and finally between the sidesurfaces of a guide depression I11 (Figs. 2 and ,20) formed in aninwardly-bent upper portion of the door I54.

After the web of the receipt material I29 has thus been positioned, theupper closure I55 is; closed, as shown in Fig. 2, to form a protectingguide for said material. The drawer 'I5I may then be moved from openpositionto closed position, in which the guide depression I11, incooperation with a matching depression I19 in the cabinet 34, providesan exit guide chute for the receipt material I29. Closing the drawer I5Imoves the feed rollers I16 directly beneath and into resilientengagement with corresponding pressure rollers I19 secured on ashaft I80supported by a shiftable framework I8l 'urgedid'owm wardly bycompressible springs I82 to normally maintain the receipt material I29in yielding engagement with the feed rollers I19 for the purpose ofadvancing said receipt material upon operation of said feed rollers, aswill be explained presently.

Directing attention to Figs. 1, 7, and 9, the left plate I53 of thedrawer I5I has secured thereto a stud I85, which pivotally supports animpression hammer operatin arm I86 having contiguous thereto a receiptfeed operating arm I81 with a slot I88, which engages the stud I topivotally and shiftably mount said. arm I81. The arm I81 has a slot I89parallel with the slot I88, which engages a stud I99 (Fig. 9) in the armI86, to form a driving connection between said arms. The arm I86 has adepending finger I9I, which cooperates with a driving stud I92 in thelever 45, which, as previously explained, is connected to the keycoupler 42 (Fig. 4) for operation in unison therewith. The stud I92extends through a clearance slot I83 (Figs. 2 and '1) in the right plate3i. The arm I81 has a shoulder I93, which likewise coacts with the studI92, which stud forms an operating connection between said arms I8 and I81 and the lever 45.

By referring to Figs. 1,5, and 1, it will be understood that the studfor the lever 94 is in axial alinement with the key coupler shaft 43 andthat, when the receipt drawer I5I is closed, the stud I85 is in axialalinement with said stud 95 and said shaft 43.

Initial counter-clockwise movement of the key coupler 42 and the lever45 (Figs. 4, 7, and 9) causes the stud I92, in cooperation with theshoulder I93, to carry the arm I81 and its companion arm I86counter-clockwise in unison therewith, and clockwise return movement ofthe lever 45 causes the stud I92, in cooperation with the finger I9I, toreturn the arm I86 and its companion arm I81 clockwise in unisontherewith to home position, as shown here, for the purpose of operatingthe inking ribbon mechanism; the impression hammers, the consecutivenumber advancing mechanism, and the receipt feeding mechanism, as willbe explained presently.

The arm I81 carries a stud I94 (Figs. 7 and 9), which pivotally supportsthe inward end of a link I95, the forward end of which is pivoted on astud I96 in a downward extension of a segment I91 (see also Fig. 1)rotatably supported by a stud I98 secured in the left side plate I53 ofthe receipt drawer I5I. The link I95 has a curved slot I 99, engaged bya stud 200 in the rearward end of an On-and-Ofi lever 20I free on a stud202 secured in the left plate I53. A spring 293 (Fig. 7) is tensioned tourge the lever 29! in a clockwise direction to yieldingly maintain thearm I81 in its downward position, as shown here, so that the shoulderI93 is normally in the path of the operating stud I92.

Moving the On-and0ff lever 20! (Figs."'? and 9) from On position, asshown here, counterclockwise against the action of the spring 203 to Offposition, through the stud 299 in cooperation with the slot I99, raisesthe link I95 and the arm I 81 to move the operating shoulder I93 aboveand out of the path of the operating stud I92 to 'disconnect said armI81 and its companion arm I86 from the lever 45, to prevent operation ofthe receipt printing and issuing mechanism.

If desired, any suitable retaining mechanism may be used for yieldinglyretaining the On-and- Off lever 20I inits Off positionfor the purpose ofthrowingoff or :disablingrtheweceipt printingand "issuin mechanism:during certain operations of the machine.

When the O'n-and-Ofi'lever 2llI (Figs. 1 and 7) isrin: On position, thestud .290 is in thepath of a right-angle bracket 2Il secured .to theouter surface of the right plate 3| to secure the receipt materialdrawer I5I aagainst'opening under such circumstances. Moving the lever20I to'Ofi positionrlifts thestud 296.0ut-of the path of the bracket 2,so thatthe-drawer I5! may; be

opened .Mechanism governed by the controllever I I1 (Fig; 2) isprovidedrforlocking .the arm I81 and connected mechanism, including theOn-and-Off lever r2llI; against movement to On position except when saidcontrol lever I I1 isinieither Read or Reset position.

Asrpreviously explained, when the control lever I.I"I :(Eigs..'7., 12,and .13) is .in other than Read or .Reset position,.thecam slot .I I2 inthe disk H3, in cooperation with the stud III, retains the lever I09 inits counter-clockwise .position, .as shown here:. When the lever I09 isin its counterclockwise position; .9, stud 294 in'a downward ithe'leverI99 clockwise totherposition shown in Fig.2, .to'move'th'e stud 204 outof the path of the car 295 to free the arm I81;for upward movement underinfluence of the On-and-Off Ilever 2BI (Fig. 7) when said lever ismovedto Off position;

When the control lever II'I (Figs. 2, '7, 12, and 13) is in other thanRead or :Reset position, a

studi206, carried vZby the lever I09, .is in the path of a'bracket'201securedto'the left side plate I53 of the receipt drawer I5I to preventthe.

opening ofsaid drawer. Moving the control lever II I to either Read or-Reset:position rocks the lever I 09 and the stud 206 clockwise to movesaid stud out of thepath of the bracket .201., so that the drawer I 5 Imay be opened. Obviously, move- I ment of the control lever I I1 fromeither .Read orLReset positiOn -to "any other position, while the drawer'I5I is open; moves the stud 206 into the path of the bracket 20'! toprevent the closiirg of. said: drawerunder such conditions.

The arm I81 (Figs. 7 and 9) has "a" guide slot 208, whichengages affixedstud .209jin the left sides-plate I53 of the drawer I5l (Fig; 2) whenisaidiarm I8! 'isnock'ed'countereclockwise, to insure that the shoulderI93 'remains'in the path of the-stud I92-andito obstruct movement of theOn-and-Off lever 2M to Offitposition after machine operation has begun.

From theforegoing description, it is evident that it is impossible toopen the receipt drawer I 5| (Fig.2).when'the control lever III(Fig..12) is in other than Read:or Reset position, and it is-alsoevident .that it isimpossible to fully close thewdrawer whensaidicontrollever -I I1 is .in other than Read or :Reset position.

With the control lever H1 in Read or Reset position and the On-and-Offlever 21H (Figs. land '7) in On position, as shown here, closing the.receipt mechanism drawer I5I- causes a camming surface 21 0,iormed on..the lower. edge rioi.

Impression hammer mechanism "Iheimpression hammers I9 and I22"(Figs.-.1,"2, and '7) comprise, respectively, rightand lefthand yoked arm'sconnected'by bails 216 and2I'I,

'said'arms'being pivoted on a rod 2I8 supported by the side plates I53of the receipt mechanism drawer I5I. 'The left-hand arm of theelectrohammer'l22 has ashoulder 2I9, which coacts with a right-angledextension 229 on an operating arm 22I free on the rod 2I8. A spring 222,tensioned between the left arm of the hammer I22 andthe arm 22 I, urgessaid parts toward each other to normally maintain the extension 226 inyielding engagement with the shoulder 2I9, asshown in Fig. 18. Ahammer-operating spring 223, tensionedbetween the arm 22I :anda'stationary stud, urges said arm and the electrohammerl22 clockwise tonormally maintain said arm 22I in yielding engagement with a stop stud224 secured in the left'side plate I53 of the drawer I5I. The arm 22I(Figs. '7 and 16) has a bent-over ear 225, which cooperates with ashoulder 226 formed on a hammer-actuating pawl '22! free on a stud '228in the arm I86. A spring 229, tensioned between the pawl 221 and an arm230 free on the stud 228, urges said parts-in opposite directions tonormally maintain a bentover ear 23I on said arm 230 in yielding contactwith the outward edge of the pawl 221. The lower end of the arm 23!)(Figs. '7 and 16) has a cam slot 232, which embraces a stud 233 'fast inthe left plate I53, said stud'233 being in substantially axial alinementwith the stud I90, when the arms I86 and I8! are in home position(compare Figs. 7 and 9).

Initial counter-clockwise movement of 3 the impression operating arm I86(Figs; 1, '7, and 16), through the stud 228, carries the pawl'221 andthe arm 230 counter-clockwise in unison therewith.- Counter-clockwisemovement of the pawl 221, through the shoulder 226, in cooperation withthe ear 225, carries the arm 22I and the electrohammer I22counter-clockwise in -"unison therewith against the action of the'spring223 to stretch said spring and to cock said electroh'ammer. After theelect rohammer I22 has been sufficiently cocked, the cam slot 232 (Figs.16 and 17) in cooperation with the stationary stud 233, rocks the arm23!) and, through the ear 23I, the pawl 22'! clockwise to disengage theshoulder 226 from the ear 225 to release the arm 22I and theele'ctrohammer I22 to the action of the hammer spring 223 (Fig. '7). Thespring 223 is of sufiicient strength to return the arm such movement ofsaid arm 22I is terminated by engagement thereof with the stop stud 224.The spring 222,: which forms a yieldable connection between the arm 22Iand the left arm of the hammer I22, is sufficiently weak to permit saidhammer I22 to travel by its own momentum a slight distancecounter-clockwise independently of the arm 22I, and during thisindependent movement-the platen .01. impressionblock of said hammer I22carries the receipt material I29 and the inking ribbon I23 (Figs. 1 and'7) into sharp contact with the electro I2l to print the data thereonupon the face of the issuing receipt.

In Fig. 1'7, the arm I86, the pawl 227, and the arm 23!] are shown infully-operated or counter-clockwise position, in which position theshoulder 226 is disengaged from the ear 225 of the arm 22I to operatethe electrohammer in the manner explained above. Clockwise returnmovement of the arm I86 from the position shown in Fig. 17 to thepositions shown in Figs. '7 and 16 causes the shoulder 226 of the pawl227 to by-pass the ear 225, whereupon the spring 229 returns saidshoulder into the path of said ear in preparation for the next machineoperation.

While some of the parts are not shown in detail, the amount andconsecutive number impression hammer 79 (Figs. 1 and '7) has on its leftarm a shoulder, similar in every respect to the shoulder 2!!! on theleft arm of the hammer I 22, which cooperates with a right-angledextension of a hammer-operating arm 234, said extension similar in everyrespect to the extension 220 of the hammer-operating arm 22I. The arm234 has a bent-over ear 235 (Figs. '7, 16, and 17), which coacts withthe shoulder 226 as explained for the ear 225, to operate the impressionhammer 79 in exactly the same manner as explained for the hammer I 22.It will be noted that the ear 235 (Figs. '7 and 16) is offset inrelation to the ear 225, so that the impression hammer 79 will notoperate until immediately after the impression hammer I22 has completedits operation, thus obtaining a better operating condition bydistributing the vibration and jar in connection with the impressionstroke of the hammers. An upwardly-extending finger 236 (Figs. '7 and16) of the pawl 227 coacts with the ear 235 to determine thecounter-clockwise position of said pawl 227 and the shoulder 226 inrelation to said ear 235 and the ear 225 for the arm 22I.

Anti-rebound mechanism for hammers The impression hammers 79 and I 22(Figs. 1, '7, and 18) are provided with an anti-rebound mechanism toprevent blurring of the impression by rebounding strokes of saidhammers. In the present disclosure, the anti-rebound mechanism is shownonly in connection with the electrohammer I 22. However, there is asimilar rebound mechanism for the consecutive number and amount hammer79. I

The anti-rebound mechanism functions after the impression blows of thehammers have beencompleted and prevents repeat or rebounding blows ofthe hammers, thereby eliminating the possibility of a double print or ofthe blurring of the printed data upon the receipt.

In Fig. '7, the hammers 79 and I22 are shown at the instant the receiptmaterial and the inking ribbon are impressed against the electro and thetype wheels to make the printed record. This is not the normal positionof said hammers, as they immediately rebound and are retained in normalposition, as shown in Fig. 18, by the antirebound mechanism.

The left arm of the electrohammer I22 has a downward extension 239 witha right-angled ear 249, which coacts with a corresponding ear. 24I on ananti-rebound pawl 242 free on a stud 243 in the left plate I53 of thereceipt drawer II. A compressible spring 244, compressed between theanti-rebound pawl 242 and a companion latch 245 free on a stud 246 inthe left 18 plate I53, urges said parts clockwise to cause said pawl 242to coact properly with the car 240 and to cause said latch 245 to coactproperly with the ear 24I on said pawl 242.

When the electrohammer I22 is in normal or rebound position, as shown inFig. 18, the ear 240 thereon is engaged by the ear 24I 0n the pawl 242to obstruct a repeat clockwise movement of said hammer I22 after theimpression stroke has been completed. When the pawl 242 is effective, asshown in Fig. 18, a surface 247 on the latch 245 engages the ear 24I tolimit the clockwise movement of said pawl 242 under influence of thespring 244. With the hammer I22 in normal position (Fig. 18),counter-clockwise cocking movement of said hammer, in the mannerexplained above, causes a downward surface on the extension 239 toengage a stud 248 in the pawl 242 and rock said pawl counter-clockwiseagainst the action of the spring 244 until the ear 24! moves beyond adownward shoulder 249 on the latch 245. After the ear 24I moves beyondthe shoulder 249, the spring 244 urges the latch 245 clockwise to movesaid shoulder 249 over said ear 24I to latch the anti-rebound pawl 242in ineffective position.

As previously explained, after the hammer I22 has been cocked, theshoulder 226 (Fig. 17) on the pawl 22'! is rocked out of engagement withthe ear 225 on the arm 22I to release said arm and said hammer I22 tothe action of the spring 223, which spring immediately urges said partsclockwise for the impression stroke. Clockwise movement of the hammerI22 causes the ear 249 (Figs. '7 and 18) to engage a rearward surface250 on the nose of the latch 245 to carry said latch counter-clockwiseto disengage the shoulder 249 from the ear 24I, whereupon the spring 244immediately urges the pawl 242 a slight distance clockwise until theupper surface of the ear 24l contacts the lower edge of the ear 240. Thecontact of the platen of the hammer I22 with the electro I2I (Fig. '7)causes said hammer to rebound a slight distance in a counterclockwisedirection to move the ear 240 out of the path of the ear 24I, whereuponthe spring 244 completes clockwise movement of the pawl 242 to theposition shown in Fig. 18, in which position said ear 24I, incooperation with the ear 249, obstructs a rebounding clockwise movementof the hammer I22, thus preventing a repeat print or a blurring of theprinted matter on the face of the receipt.

A similar anti-rebound mechanism (not shown) is provided for the hammer79 to prevent rebounding of said hammer after the impression stroke.

The rebound-preventing mechanism shown in Figs. 7 and 18 of the presentdisclosure is simi- 60 lar in many respects to the rebound-preventingmechanism shown in Figs. 1 and 11 of the United States Patent No.2,342,082, issued February 15,

1944, to Joseph J. Klosterman.

Receipt-feeding mechanism Byreferring to Figs. '2 and 9, it will berecalled that the arm I87 is connected by the 1ink-l95 to the lower endof the receipt-feeding segment I91, which segment is rotatablysupportedby the stud I98. The segment I91 (Figs. 1, 9, '10, and 11) has,on its periphery, teeth which .mesh with corresponding teeth in a pinion252 secured on a sleeved portion of a disk 253, said sleeved portionbeing rotatably supported on a receipt feed shaft 254 journaled in hubssecured in the side plates I53 of the receipt drawer II. The shaft 254has secured thereon the two receipt feeding rollers I16, which coactwith the corresponding pressure rollers I19 when the receipt drawer I5Iis-closed. The disk 253 (Figs. and 11) carries a stud 255, whichrotatably supports a receipt feed pawl 256 urged counter-clockwise by ator sion spring 251 to normally maintain the tooth of said pawl inengagement with an operating notch in the flanged portion of a feed drum258.secured on the shaft 254.

Integral with the drum 258 (Figs. 9, 10, and 11) is a positioning disk259 having a stop notch engageable by the upper end of a stop pawl 269free on the stud I98, and having another step notch engageable by theupper end of a stop pawl 26I free on a stud 262 in the left plate I53. Aspring 253, tensioned between the pawls 269 and 261, urges said pawls inopposite directions or-toward each other to normally maintain theirupper ends in yielding engagement with the corresponding notches in thedisk 259 to locate and hold the shaft 254 and parts thereon in homeposition.

By referring to Figs. 1 and 10, it will be remembered that the pressurerollers I19 maintain the web of the receipt material I29 in yieldingcontact with the feed rollers I16, and it will be noted that both setsof rollers have their peripheries serrated or knurled to form fine teethto better feed the receipt material.

Initial counter-clockwise movement of :the key coupler 42 and the lever45 (Figs. '7 and 9), through the stud I92, in cooperation with theshoulder I93, carries the arm I81 in unison therewith throughapproximately 26 /2 degrees of movement. Counter-clockwise movement ofthe arm I81, through the link I95, rocks the segment I91counter-clockwise in unison therewith. Counter-clockwise movement of thesegment I91 revolves the pinion 252, the disk 253, and the pawl 256clockwise, as viewed in Fig. 9, and I counter-clockwise as viewed inFig. 11. During this idle or take-up movement, the outside surface ofthe pawl 256 wipes freely over the internal periphery of the flange ofthe drum 258 without imparting any movement .to said drum, the shaft254,and the feed rollers I16 (Fig. 10). As the segment I91 (Fig. 9) nearsthe terminus of its initial'counter-clockwise movement, a roller 264carried thereby engages an inside surface on the pawl 269 and rocks saidpawl counter-clockwise against the action of the spring 263 out ofengagement with the corresponding stop notch in the disk 259 to free.Said disk and the shaft 254 for feeding movement in a counter-clockwisedirection, as viewed here. During its initial movement, the segment I91imparts a complete counter-clockwise revolution to .the pinion 252, thedisk 253, and the pawl 256, as viewed in Fig. 11, to cause said pawl toagain engage the notch 25I in the flange of the drum 258, as shown here.

, With the pawl 256 engaged with the notch 25] in the flange of the drum258 and with the pawl 260 disenga ed from its notch in the .disk 259,

clockwise return movement of the segment I91,

under 'influence of the arm I81, revolves the pinion 252, the disk 253,and the pawl'256 counter-clockwise, as viewed in Fig. 9, and clockwise,as viewed in Fig. 11. This movement of the disk 253 and the pawl 256causes said pawl, in cooperation with the notch 25 I to carry the drum258, the disk 259, the shaft 254,'and the feed rollers I16 in unisontherewith one complete revolution to feed the web I29 of the receiptmaterial forwardly as viewed in Figsl, 2, and 9. This moves the printedportion of said receipt material the proper distance beyond the edge ofa tearing blade or knife 265 (Fig. 2) secured in the framework for thepressure rollers I19, which blade is used for tearing or separating thefinished receipt, shown in Fig. 19, 'from the web .I 29.

As the shaft 254, the drum 258, and the disk 259 complete theircounter-clockwise feeding movement (Fig. 9), the stop and locatingnotches in said disk 259 are again engaged by the upper ends of theircorresponding pawls 259 and 26I'to locate and hold the feeding mechanismin normal or home position. It will be noted in this respect that thepawl 26I prevents retrograde movement of the disk 259, the drum 258, andthe shaft 254 during initial movement of the segment I91 and the pinion252, and that the pawl 269 prevents feeding movement of said parts.until after said segment I91 and said pinion 252 have completed theirinitial movements.

It will be remembered that movement of the On-and-Ofi lever 29Icounter-clockwise from On position, as shown in Fig. '7, to Offposition, through the stud 299, in cooperation with the slot I99, liftsthe link I95 and the arm I81 to move the driving shoulder I93 of saidarm out of the path of the stud I92 to disable the impression mechanismand the receipt-feeding mechanism.

A receipt-feeding mechanism similar in many respects to that disclosedin the present application is disclosed in Figs. 8, 9, and 10 and thedescription thereof in the previously-referred-to United States PatentNo. 2,342,082.

- Consecutive number, inking ribbon, and type wheel aliner drivingmechanism By referring to Figs. 1, 5, and '1, it will be .recalled thatthe fixed stud 95, which rotatably supports the operating lever 94 forthe consecutive number, inking ribbon, and type aliner mechanisms, is inaxial alinement with the key coupler shaft 43 and also with the stud Iwhen the receipt material drawer I5I is closed. The lever 94 carries astud 266, which is engaged by an operating notch 261 in the arm I86 whenthe drawer I5I is closed. Consequently, rocking movement, firstcounter-clockwise and then back to normal position, of the arm I86 rocksthe lever 94 and, through the link 93, rocks the crank 92 and the shaft66 first counter-clockwise and then back to normal position, in unisontherewith, to advance the consecutive number type wheels 89 (Fig. 14),to actuate the ribbon feeding mechanism (Fig. 7) and to actuate thealiner 11 (Fig. 5') in the manner explained earlier herein.

It will be noted that the notch 261 in the arm I86 for the stud 266(Figs. 5 and '7) is flared at its open end to permit easy engagement ofsaid notch with said stud in case of any misalinement between said partswhen the receipt drawer I5I .is moved from open position to closedposition.

The On-and-Off lever 201 (Figs. 1, 2, and 7), which controls thereceipt-feedingand impression mechanisms, likewise controls theoperation oi the consecutive number mechanism, the ink ribbon mechanism,and the type wheel aliner mechanism, which mechanisms are all operatedby the arms I86 and I81 (Figs. 7 and 9), which are in turn directlycontrolled by said On-and-Oif lever 20!.

Summarizing briefly, it will be understood that the present invention isdirected to novel receipt printing and issuing mechanisms which arecontained in a sliding magazine or drawer which may be moved outwardlyfrom closed or working position to open position for the replenishing ofthe receipt material supply, which in the present instance is containedin a compact fanfolded package. The receipt material supply may beinserted in a convenient opening in the front of the receipt materialdrawer, access to said opening being had by a convenient closuretherefor. Likewise, the receipt material drawer and its contents may bereadily and easily removed from the machine in case it is desirable ornecessary to adjust or repair the receipt impression and/or feedingmechanisms.

The present machine is provided with the usual manually positionablecontrol lever for controlling the various functions of said machine, andonly when said control lever is in either Read or Reset position is itpossible to move the receipt drawer from closed position to openposition or vice versa. The operation of the impression mechanism andthe receipt-feeding mechanism is controlled by an On-and-Off lever whichis likewise under control of the machine control lever, and saidOn-and-Off lever is locked in On position except when the control leveris in either Read or Reset position. The On-and-Off lever likewisecontrols the opening of the receipt drawer, and it is necessary thatsaid lever be in Off position before the drawer may be moved from closedposition to open position. However, the On-and-Off lever does notcontrol the closing of the receipt drawer, as said drawer may be closedregardless of which position said lever is in.

It is believed that a further statement of operation in connection withthe receipt printing and issuing mechanism of the present invention isunnecessary in the present instance, as a full understanding of suchoperation will have been obtained from a careful reading of thepreceding specification.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form orembodiment herein disclosed, for it is susceptible of embodiment invarious forms, all coming within the scope of the claims which follow.
